I used the 2.0 glTF import with great results, but I am with some doubts:
After the importation beside the separated elements in renders, materials and textures, there are the Template, Container and Model(source), being that, Container and Model(source) have a Re-Import option in the right click menu. How this option work?
When I builds the project, I saw that its size is the double of the GLB size, may I delete the Model(source) to reduce it?
Re-import is the same as drag and dropping the file anew on the assets panel. It will recreate and overwrite if required, all generated assets. Useful if you’ve removed them or made changes (e.g. to materials).
You can do that, the only thing you will lose is the references between the generated assets and the model source. That means if you plan to update the model and have the assets updated, that will not be possible. Uploading the model afterwards will create duplicate assets.
